8-Input Priority Encoder
coded output. The output code is that of the highest order input. Any input
of lower priority is ignored. Each output incorporates a latch allowing
synchronous operation. When the clock is low the outputs follow the
inputs and latch when the clock goes high. This device is very useful for
a variety of applications in checking system status in control processors,
peripheral controllers, and testing systems.
when input D0 is high). The Q3 output is high when any input is high. This
allows direct extension into another priority encoder when more than
eight inputs are necessary. The MC10165 can also be used to develop
binary codes from random logic inputs, for addressing ROMs, RAMs, or
for multiplexing data.
